Package and route
Packing notes
Listed export packaging includes 1 L, 2.5 L, 3.75 L, 4 L, 5 L, 12-can or 18-can carton options, 20 L, and 200 L packs.
Confirm whether packaging is metal can, plastic pail, drum, or cartonized retail pack.
Request pallet configuration, net weight, gross weight, dimensions, and container loading quantity.
Confirm export marks, batch labels, production date, shelf-life marking, and language requirements.
Ask whether samples are available and whether sample shipment follows DG or non-DG declaration after SDS review.
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Sourcing 1K acrylic binder for automotive basecoat manufacturing or tinting systems
Evaluating binder options for pearl, silver, metallic, or basecoat product lines
Comparing Chinese automotive coating binder suppliers for export procurement
Private-label automotive paint component sourcing with document verification
Distributor qualification where SDS, TDS, COA, packing, and DG status are required before RFQ
How we compare
Sourcing options
Request a document-first RFQ with TDS, SDS, COA, formulation category, and DG classification before price negotiation.
Ask for a small compliant sample lot for compatibility and QC testing before container purchase.
Compare 1K binder versus 1K mixed resin grades from the same supplier and confirm performance differences by specification, not marketing claims.
Source in 20 L pails for distributor trials or 200 L drums for bulk import, subject to DG and shelf-life review.
Consider supplier audit, third-party inspection, and retained sample agreement for repeat shipments.
Human review
Compliance notes
CAS/spec verification is required: CAS 9003-01-4 commonly refers to poly(acrylic acid), while the listed formula CH2=CH-COOH and EINECS 201-177-9 correspond to acrylic acid; this may not accurately describe a solvent-based automotive binder mixture.
Request current TDS, SDS, COA, composition disclosure range, VOC data, flash point, solvent list, resin solids, viscosity, acid value, and density before purchase.
Do not rely on the marketplace title or basic listing data for import classification; confirm HS code, DG class, UN number if applicable, packing group, and marine pollutant status from the supplier SDS.
Automotive coating binders may contain flammable solvents or regulated VOC components; confirm transport mode eligibility for sea, air, rail, and courier sample shipments.
Confirm whether the product is supplied as resin, binder, mixed resin, finished coating component, or additive, because import and labeling requirements may differ.
Check destination-market requirements for chemical inventory status, GHS labeling, VOC limits, REACH/UK REACH, TSCA, K-REACH, AICS/AIIC, DSL/NDSL, or local chemical notification as applicable.
Supplier certification claims such as ISO9001 and ISO14001 should be verified with valid certificates and scope covering coating resin or automotive paint production.
No regulatory guarantee is implied; buyer should validate product classification, permitted use, and import obligations with qualified compliance personnel.

Questions to confirm
Please provide the latest TDS, SDS, and COA for the exact 1K binder grade being quoted.
Is CAS 9003-01-4 the intended resin CAS, or is the product a mixture containing acrylic resin, solvents, and auxiliaries? Please clarify CAS numbers for major components.
What are the resin solids percentage, viscosity range, acid value, density, flash point, VOC content, and solvent composition range?
Is this product designed only for 1K basecoat systems, or can it be used in pearl, silver, metallic, and solid color systems?
What impurities or restricted substances are controlled, such as benzene, toluene, xylene, heavy metals, formaldehyde, phthalates, or residual monomer?
What is the confirmed shelf life and recommended storage condition stated on the current TDS?
What packaging sizes are available for export orders, and what are the net/gross weights per unit?
Is the material classified as dangerous goods for sea or air freight? If yes, please provide UN number, DG class, packing group, and transport name.
